Clinical Trial Summary

This study was performed to compare endodontic regeneration outcome in necrotic mature single rooted teeth with periapical radiolucency using platelet rich fibrin (PRF) & concentrated growth factor (CGF) as a different natural scaffold by evaluation of: - Regaining pulp sensibility by thermal test (hot and cold) - Periapical healing using digital radiography and selected samples will be evaluated using Cone Beam Computed Tomography (CBCT).


Description:

The current study was designed as randomized controlled clinical trial with an allocation ratio 1:1 and conducted in the clinic of Endodontic Department, Faculty of Dental Medicine for Girls, Al-Azhar University. The study was designed, analyzed and interpreted according to the Consolidated Standards of Reporting Trials (CONSORT 2010) checklist of information. Ethical approval for the human research was obtained in accordance with guidelines from Research Ethics Committee (REC) of the institute with the code number: P-EN-21-02. All patients read and signed an informed consent form with details about the study along with the benefits and risks of the therapy (Appendix A).A total of thirty-six patients were examined for this study. After clinical and radiographic examinations only eighteen patients from cases that were fulfilling the inclusion criteria were selected according to sample size calculation. Eighteen cases was divided randomly into two groups (9 cases each): Group I (PRF group): Preparation of PRF: Five ml blood was drawn from the patient's right median cubital vein into a test tube without the addition of an anticoagulant and centrifuged immediately at 3000 rpm for 10 minutes Group II (CGF group): Preparation of CGF: Ten ml of intravenous blood sample from the patient will be obtained and placed in centrifuge tubes without anticoagulants; accelerated for 30 seconds; centrifuged at 2700 rpm for 2 min, 2400 rpm for 4 min, 2700 rpm for 4 min, and 3000 rpm for 3 min; and decelerated for 36 secs to stop. Methodology: Common treatment protocol will be as follow: First visit: tooth was isolated using rubber dam followed by access cavity preparation and working length determination. Mechanical preparation of root canal was performed using rotary instrumentation then the canal was irrigated by 1.5% NaOCl between each successive file. After drying the canal with paper point, Calcium hydroxide as intracanal medicament was placed. The access cavity was sealed with a cotton pellet and glass ionomer cement for three weeks. Second visit: plain anesthesia without a vasoconstrictor was administrated. Glass ionomer was removed under the isolation with rubber dam. Calcium hydroxide was flushed from the canal using 5ml sterile saline followed by irrigation using 20ml of 17% ethylene diamine tetra acetic acid (EDTA) then drying the canal using paper point. Intentional over-instrumentation 3 mm beyond the apex was done using sterile #35 k file to induce bleeding inside the canal followed by placement of PRF and CGF inside the canal in group I and group II respectively followed by placement of 3 mm mineral trioxide aggregate (MTA) below cementoenamel junction and the coronal cavity will be sealed using composite. The regeneration outcome will be evaluated 6 month and 1 year follow up, clinically using thermal test to ensure the restoration of pulp sensibility or not and radiographically using digital radiograph to assess the periapical healing. Selected samples will be evaluated using Cone Beam Computed Tomography (CBCT).

Outcome

Type Measure Description Time frame Safety issue
Primary healing The elimination of symptoms and the evidence of periapical bony healing assessed radiographically (incidence of bone formation at the apex of root which indicate complete healing of chronic periapical abscess which assessed by periapical radiograph and cbct at 6 months & 1 year after treatment , as it appear radiolucency in radiograph which decrease by time that indicate complete healing of abscess and reformation of bone apically 1 year
Secondary regaining of pulp sensibility restoration of normal pulp sensation assessed by thermal test (hot using hot water in plastic syringe & cold using endo ice ) after isolation of the tooth.. thermal test was done before treatment then 6 month &1 year follow up and ask the patient about his sensation 1 year
